Specication of Letters Patent.

Patented Feb. 2S, 1911.

Application led ctober 31, 1910. Serial No. 589,942.

To all whom it may concern:

Be it known that I, ALoIs ToMIscHKA, subject of the Emperor ofAustria-Hungary, residing at Mdling, near Vienna, Austria- Hungary, haveinvented certain new and useful Improvements in Fire-Arms, of which thefollowingis a specification.

It is already known to connect the barrel of fire arms with the actionbody by means of a dove-tail and to secure the barrel in its position byspecial connection means.

According to the present invention however all further connectingdevices are rendered superfluous by fitting the barrel from the rear ofthe re arm in an appropriately grooved forwardly closed portion of thestock or action body by means of va special lug and holding it frommoving beyond its extreme forward position by means of the hook-shapedend of this lug. A barrel arrangement of this kind is shown by way oferample on a self-loading pistol in the accompanying drawing vin which:

Figure l illustrates the pistol in side elevation. and partial section,after firing, Fig. 2 the manner of fitting the barrel in the action bodyand Fig. 3 shows the pistol in plan view on a reduced scale with thebreech closing block retracted.

The barrel b which during firing remains stationary is fitted by meansof a projection or lug c in an appropriately grooved forwardly closedportion dof the action body e and is held from being moved forwardbeyond its eXtreme forward position by the hookshaped end c on theprojection c` without the use of additional connecting devices.

Upon disassembling the fire arm for the purpose of cleaning, the barrelb' is slid back until its projection c is free from the groove of theaction body el.

Claims: l

l. A lire-arm comprising a body portion having a groove closed at itsforward end and a barrel having a single projection conforming to saidgroove, said projection having a hook-shaped rear end extending belowthe projection and adapted to abut against a lixed part of the body infront of said end when the parts are in position for firing, for thepurpose specified.

2. A tire-arm comprising a body portion having a longitudinal grooveclosed at its forward end and a barrel having a longitudinal projectionon its under side conforming to and adapted to slide in the groove andabut against the closed end 0f the latter when the parts are in positionfor firing, said projection having a hook-.shaped rear end portionextending below the projection adapted to engage a fixedpart of the bodyportion in front of said end to prevent the barrel from moving beyondits extreme forwardposition. l

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. 4
